Then Re-open the dashboard for editing, set the Resolution time less than 15 seconds and save it. However, the Resolution set back to 15 seconds.

Environment:

APM 10.x

Cause:

Introscope Enterprise Manager goes through a "harvest" cycle every 15 seconds, the minimize resolution is 15 seconds, so even if we changed the Resolution time less than 15 seconds it won't be passed to effect.

Resolution:

It is part of the design to not allow the Resolution time less than 15 seconds.
